Hofmann was born in Baden, Switzerland, the first of four children to factory toolmaker Adolf Hofmann and his wife Elisabeth (born Elisabeth Schenk). Owing to his father's low income, Albert's godfather paid for his education. When his father became ill, Hofmann obtained a position as a commercial apprentice in concurrence with his studies. At the age of twenty, Hofmann began his chemistry degree at the University of Zürich, finishing three years later, in 1929. His main interest was the chemistry of plants and animals, and he later conducted important research on the chemical structure of the common animal substance chitin, for which he received his doctorate, with distinction, in the spring of 1929.[5]

Regarding his decision to pursue a career as a chemist, Hofmann provided insight during a speech he delivered to the 1996 Worlds of Consciousness Conference in Heidelberg, Germany:

One often asks oneself what roles planning and chance play in the realization of the most important events in our lives. [...] This [career] decision was not easy for me. I had already taken a Latin matricular exam, and therefore a career in the humanities stood out most prominently in the foreground. Moreover, an artistic career was tempting. In the end, however, it was a problem of theoretical knowledge which induced me to study chemistry, which was a great surprise to all who knew me. Mystical experiences in childhood, in which Nature was altered in magical ways, had provoked questions concerning the essence of the external, material world, and chemistry was the scientific field which might afford insights into this.[6]

Hofmann became an employee of the pharmaceutical-chemical department of Sandoz Laboratories (now a subsidiary of Novartis), located in Basel as a co-worker with professor Arthur Stoll, founder and director of the pharmaceutical department.[7] He began studying the medicinal plantsquill and the fungusergot as part of a program to purify and synthesize active constituents for use as pharmaceuticals. His main contribution was to elucidate the chemical structure of the common nucleus of the Scillaglycosides (an active principal of Mediterranean Squill).[7] While researching lysergic acid derivatives, Hofmann first synthesized LSD on November 16, 1938.[8] The main intention of the synthesis was to obtain a respiratory and circulatory stimulant (an analeptic) with no effects on the uterus in analogy to nikethamide (which is also a diethylamide) by introducing this functional group to lysergic acid. It was set aside for five years, until April 16, 1943, when Hofmann decided to reexamine it. While re-synthesizing LSD, he accidentally touched his hand to his mouth, nose or possibly eye, accidentally ingesting a small amount[9] and fortuitously discovered its powerful effects. He described what he felt as being:

... affected by a remarkable restlessness, combined with a slight dizziness. At home I lay down and sank into a not unpleasant intoxicated[-]like condition, characterized by an extremely stimulated imagination. In a dreamlike state, with eyes closed (I found the daylight to be unpleasantly glaring), I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors. After some two hours this condition faded away.[10]

Three days later, on April 19, 1943, Hofmann intentionally ingested 250 micrograms of LSD. This day is now known as "Bicycle Day," because after starting to feel the effects of the drug he rode home on a bike, and that became the first intentional acid trip.[11]

It gave me an inner joy, an open mindedness, a gratefulness, open eyes and an internal sensitivity for the miracles of creation. [...] I think that in human evolution it has never been as necessary to have this substance LSD. It is just a tool to turn us into what we are supposed to be.

Hofmann, later, was to discover 4-Acetoxy-DET (4-acetoxy-N,N-diethyltryptamine), also known as ethacetin, ethylacybin, or 4-AcO-DET, a hallucinogenictryptamine. He first synthesized 4-AcO-DET in 1958 in the Sandoz lab. Hofmann became director of the natural products department at Sandoz and continued studying hallucinogenic substances found in Mexican mushrooms and other plants used by the aboriginal people there. This led to the synthesis of psilocybin, the active agent of many "magic mushrooms."[13] Hofmann also became interested in the seeds of the Mexican morning glory species Turbina corymbosa, the seeds of which are called ololiuhqui by the natives. He was surprised to find the active compound of ololiuhqui, ergine (LSA, lysergic acid amide), to be closely related to LSD.

In 1962, he and his wife Anita Hofmann (née Guanella, sister of Gustav Guanella, an important Swiss inventor) traveled to southern Mexico to search for the plant "Ska Maria Pastora" (Leaves of Mary the Shepherdess), later known as Salvia divinorum. He was able to obtain samples of this plant, but never succeeded in identifying its active compound, which has since been identified as the diterpenoidsalvinorin A. In 1963, Hofmann attended the annual convention of the World Academy of Arts and Sciences (WAAS) in Stockholm.

Hofmann, interviewed shortly before his hundredth birthday, called LSD "medicine for the soul" and was frustrated by the worldwide prohibition of it. "It was used very successfully for ten years in psychoanalysis," he said, adding that the drug was misused by the Counterculture of the 1960s, and then criticized unfairly by the political establishment of the day. He conceded that it could be dangerous if misused, because a relatively high dose of 500 micrograms will have an extremely powerful psychoactive effect, especially if administered to a first-time user without adequate supervision.[14]

In December 2007, Swiss medical authorities permitted psychotherapist Peter Gasser to perform psychotherapeutic experiments with patients who suffer from terminal-stage cancer and other deadly diseases. Completed in 2011, these experiments represent the first study of the therapeutic effects of LSD on humans in 35 years, as other studies have focused on the drug's effects on consciousness and body.[15] Hofmann acclaimed the study, and continued to say he believed in the therapeutic benefits of LSD.[16] In 2008, Hofmann wrote to Steve Jobs, asking him to support this research; it is not known if Jobs responded.[17] The Multidisciplinary Association of Psychedelic Studies (MAPS) has supported research in the field of psychoanalysis using LSD, carrying on Hofmann's legacy and setting the groundwork for future studies.[18]

Hofmann was due to speak at the World Psychedelic Forum[19] from March 21 to March 24, 2008, but was forced to cancel because of bad health.

Hofmann died of a heart attack on April 29, 2008 and was survived by several grandchildren and great-grandchildren. He and his wife, Anita, who died in 2007, raised four children, one of whom died at the age of 53.[21]
